-You need to know the following:
-" RX1 is connected to ground.
-" TX1 is not connected.
-" CLKO is not connected.
-" Setting the OCR register to 0xFA is a good idea.
- This means normal output mode , push-pull and the correct polarity.

You will probably also want to set the clock divider value to 0 (meaning divide-by-2),
the Pelican bit, and the clock-off bit (you have no need for CLKOUT anyway.)
